I was wondering... I saw some 120-12.6 volt transformers at radiosnack, if I used 3 reversed in series, and used 12 volts AC to power them, would they give me ~12,000 volts or short out somewhere along the way. I am trying to make a circuit that generates small sparks. I was thinking a large one (~3 amps) first, then small ones (~1 amp) for the higher voltages. I know they aren't designed for high voltages, but would they work? They only need to last for a week or 2.
